HOSE-NOZZLE BRUSH.

To all whom it may concern:

Be it known that we, NORMAN,J. SMITH and VILLIAM F. LIZER, citizens of the United States of America, and residents of lVaterloo, Blackhawk county, Iowa, have invented certain new and useful Improve ments in Hose-NozzleBrushes, of which the following is a specification.

Our invention relates to improvements in hose-nozzle brushes, and the object of our improvement is to provide a rotary head upon a perforated hose-nozzle, said head having a brush-like outer part, and said head rotated by means of water actuated mechanism contained within the nozzle. This object we have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which:

Figure 1 is a vertical axial longitudinal section of our said improved device, with parts broken away. Fig. 2 is a vertical transverse section of the device shown in Fig. 1, taken on the line ab thereof, and looking in the direction of the arrow.

Similar numerals of referencedenote corresponding parts throughout the several views.

The numeral 19' denotes a tube, one open end of which is provided with a coupling 7 part 20 for a hose or a pipe. The other end of the tube is conically expanded at 18, and closed by a partition or transverse wall 14:.

The numeral 10 denotes a hollow cylindrical chamber having one end annularly thickened at'11. This thickened part is detachably secured to an outwardly flanged part of the chamber 18 by means of screws 12.

The partition wall 141 has on its left-hand face a bearing 15 in which is seated the right-hand end of a rotary shaft 1 having three turbine-wheels 2-1 mounted thereon in spaced relation, and having outwardly directed V-shaped vanes 22. The numeral 13 denotes bosses on opposite sides'of the left hand face of the partition let and which are orificed to receive the right-hand ends of tubes 16, whose left-hand ends are closed.

Each tube 16 has three spaced inwardly directed laterally inclined nozzles 17 adapted to discharge water against the vanes of said turbine or overshot wheels 21. Said chamber 10 has its left-hand end conically diminished at 9, and has a cylindrical ex- Spe cification of Letters Patent. Patented Feb.'15, 1916 Application filed February 1, 1915. I

tension 8,the end of the latter part being stopped by a closure? centrally orificed to receive the left-hand extremity of said shaft 1 therein. z

' The numeral 2 denotes a cup-shaped head provided with a plurality of orifices 3 and concentrically mounted about the chamber part 8 on the outwardly extending end of the shaft 1 by means of a screw 5 or other convenient fastening means. Brush bristles 1 are mounted all over the outside surface of thehead 2. The left-hand end of the tubular part 8 has a plurality of orifices 6., I

' Operation: When any fluid, under pressure, such as water or compressed air, is

transmitted through the hollow parts 19 6, a large proportion of the fluid then passing through the head 2 by way of its orifices 3. Since the wheels 21 are of a turbine or overshot type, and the fluid under pressure is delivered to them tangentially from without the rims of the wheels, a powerful leverage is exercised upon the shaft 1. This leverage is such that water or other fluid under a comparative little amount of head, is able to continuously rotate the brush 2% effectively while the latter is being employed in cleaning various surfaces ,and while thereby undergoing considerable friction.

The brush shown is of a type which is suitable for general cleaning purposes, but other forms may be used.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is: a c

1. In combination, 'a chamber adapted to be placed in communication with a source of fluid supply under head, a rotor mounted in said chamber and adapted to be rotated by said fluid when passing through the chamber, said chamber having a deliverynozzleprovided with a plurality of small outer end of said shaft and surrounding the peripherally orlficed part of said nozzle.

2. In combination, a nozzle adapted to be placed in communication with a supply of fluid under head, a rotary shaft in szud nozmeablebrushing-means mounted on the outside of said. body adapted to receive Water passed under PTQSSUFB'TEIOHL said nozzle through its peripheral orifices and through the peripheral orifices of said body While the latter is rotating about the nozzle.
